Trees have thin layers of cells kinda like we do, these are called cambium that lies just beneath the bark. The cambium transports water and nutrients to and from the roots and leaves. It also produces new wood and bark tissue as plants grow.. Anything that damages the bark or the underlying cambium can weaken trees and make them more vulnerable to disease and insects. Four things that damage your trees.. Weather, insects, animals and equipment.Let's talk about tree guards, when choosing a tree guard, consider the site and the kind of damage your tree is vulnerable to. When installing a tree guard leave enough room for the tree to grow. And inspect the tree guard annually to make sure the tree growth is not being restricted.Arbor guards are plastic forms that protect trees from weather, animals and equipment. These expand as trees grow and easy to install.Spiral guards are plastic strips that can be wrapped around tree trunks, they protect from weather damage and animal browsing.Texguard is a blue plastic mesh sheet, secured to ground by metal pins. These protect from animals and equipment. They don't need to be removed they just breakdown in sunlight.Paper wrap is wrapped around the tree loosely and tied by rope or string. They protect from weather damage. Burlap done the same way, will protect from weather. Hardware cloth protects trees from animals and equipment, but doesn't protect from weather. Field Tile are plastic tiles that will protect trees from weather and animals and equipment. One more solution to a serious problem, here in this area is the deer population and eating our newly planted trees and our garden. Some natural solutions are hair clippings, spraying the trees with a soapy solution of peppers and deodorant soap, also hanging dryer sheets from the trees is also suppose to help. Planting certain flowering plants and herbs can also deter deer from eating your garden and your young trees. Some of these plants are: 1. Any plants from the plant family2. Yarrow, bugleweed, bell flower, catnip, oregano, thyme, sage, lavender, daffodils, marigolds, and many others. Spreading blood meal around your trees or mixing it in with your fertilizer will keep deer away... Deer dont really like the smell of blood. Plus one last thing... making an egg solution and spraying it onto your trees will also help to deter deer and while you are at it put those egg shells around the tree, deer don't like eggs. By the way I tried a new idea... recently and it seems to be working quiet well. We put a few steel post on the outside perimeter of the garden and strung some heavy kite string around it, but we got several tin pie pans I had saved up and put holes in them and strung them through the string... they move in the wind and flash in the sunlight.. and the deer seem to avoid getting to close to the garden... Well, hope this will help all of you like myself struggling to keep my newly planted trees and garden safe from deer and rodents.
